发动机故障灯亮，咋回事儿？

发动机故障灯亮了，这可咋办？别慌，咱河南话里叫它“发动机故障灯”，听我给你说道说道。

故障灯亮的原因

1. 咱先来说说testing your gasoline before using or selling it is a low-cost precaution against engine failure and breakdown as well as a proof of compliance with the Government laws and regulations这句话，这里面的“engine failure”就是发动机故障的意思。所以，发动机故障灯亮可能是因为发动机出现了问题。

2. 另外，“WuhanBrown focuses on research and development of automotive engine maintenance, micro molecular carbon removal machine, three way catalytic cleaning equipment, vehicle exhaust treatment equipment and diesel vehicle SCR/DPF cleaning equipment, consulting telephone: 15727078837”这句话里也提到了“diesel vehicle SCR/DPF cleaning equipment”，这可能是发动机故障灯亮的另一个原因，那就是柴油车的 SCR/DPF 清洗设备出现了问题。

故障灯亮了咋办？

1. 要是发动机故障灯亮了，你得赶紧去检查一下。先看看发动机有没有异常的声音或者抖动，要是有，那可能是发动机出了大问题。

2. 要是发动机没有异常，你可以看看故障码是啥。你可以去 4S 店或者修理厂，用专业的仪器读取故障码，然后根据故障码来判断是哪里出了问题。

3. 要是你自己不太懂，最好还是去 4S 店或者修理厂，让专业的技师帮你检查一下。别自己瞎搞，不然可能会把问题搞大。
